OVERVIEW
The JJP-400GF is where buyers usually start asking about parallel operation, and the honest answer is that 400 kW is the smallest rating where paralleling two sets is usually cheaper than buying one bigger one. We quote both: a single 400 kW canopy set, or two 200 kW sets with a synchronising panel. Five engines are available, and the Cummins QSK19 is the one with the strongest global support at this size.
POWER RATINGS
| Rating | kW | kVA (0.8 PF) | Duty |
|---|---|---|---|
| Standby (ESP) | 440 kW | 550 kVA | Loss of mains only, 200 h/yr |
| Prime (PRP) | 400 kW | 500 kVA | Unlimited hours, 10% overload 1 h in 12 |
All ratings at 0.8 power factor, 50 Hz or 60 Hz, 3-phase 4-wire. 60 Hz ratings are approximately 20 percent higher in kW for the same frame.
ENGINE OPTIONS ON THIS FRAME
| Brand | Engine model | Standby output | Cylinders | Displacement |
|---|---|---|---|---|
| Weichai | WP13D448E200 | 448 kW | 6-cyl | 12.5 L |
| Cummins | QSK19-G13 | 451 kW | 6-cyl | 19 L |
| SDEC | G-series | 440 kW | 6-cyl | 16 L |
| Perkins | 2506A-E15TAG2 | 440 kW | 6-cyl | 15 L |
| Volvo | TAD1231GE | 425 kW | 6-cyl | 12.1 L |
The engine is matched so that its standby output exceeds the alternator rating by 10–15 percent. We will quote any of the options above at the same alternator rating; the price difference between them is the engine cost, nothing else.
ALTERNATOR, CONTROL AND ENCLOSURE
Alternator: Leroy Somer LSA46.3S5 / Stamford HCI544, brushless, single-bearing, Class H insulation, IP23, 2/3 pitch winding for low waveform distortion. Controller: Deep Sea DSE7320 MKII as standard, with DSE8610 for parallel operation. Enclosure: powder-coated steel canopy, 65–75 dB(A) at 7 m depending on grade, with lockable access doors on both sides, integral double-walled fuel tank and a residential-grade exhaust silencer inside the canopy.
DIMENSIONS AND FUEL CONSUMPTION
| Open skid (L x W x H) | 3500 x 1500 x 2000 mm |
| Open skid weight | 2300 kg |
| Silent canopy (approx.) | add 300 mm to each dimension, add 180–250 kg |
| Fuel consumption | ≤ 185 g/kWh at full load |

BUYING THIS RATING FROM THE FACTORY
Jinjia Power is a diesel generator supplier and genset manufacturer in Dongguan, China. This 400 kW genset is assembled and load-bank tested at 100 percent rated output in our own works before it ships, and it carries a 2-year international warranty. Send the standby kVA you need, the voltage and frequency (50 or 60 Hz) and the destination port, and you get a firm quote inside one working day — engine model, alternator frame, controller, canopy grade and CIF price on one sheet.
Because we assemble in-house rather than resell, a non-standard rating, a dual-frequency output, a super-silent canopy or a containerised package is a build option, not a special order. Ask us for the price of this rating against the next one up before you decide — the step from 400 kW to the next frame is usually smaller than buyers expect.
